[Something strange is in front of White Chalice. A large humanoid construct of metal and stone, it looks like a statue with a long cloak and a sword. It's floating... no - standing in the air above the Pacific Ocean waves, and its hand is stretched out in a "stop" sign.]

Please wait, White Chalice! There is something incredibly important I must tell you!

[This figure has a yellow gem on its forehead, and inside the gem there is... a human? He must be the pilot.]

[Some time later and after a long talk with Captain Smith the XO, the mysterious pilot and his unit are both on board. And he has something important to tell you all.]

My name is Coztic. I know it is hard to believe because I look just like you, but I am not a human. I am a member of a race called Over Being. There are others from my race on Earth, but they are hiding - and we must stop them before their plans come to fruition, because they are here to kill and enslave humanity. It is only a game for them.

... I am afraid that my race is what you would call "irredeemably evil". Me and one other are the only different ones. That other Over Being, Texotic - was captured by my evil brethren, stripped of memories and free will, and let loose to rampage on your planet. I beg you: we need to work together to save this planet from Over Being, but before that happens, we need to rescue Texotic! I know where to go, and how to do it. It won't be easy, but I know of your reputation. If there is anyone on this planet who can do it, it is you.

I have no resources or... money, to pay you with. I can only offer my services and loyalty.

[The alien - or so he calls himself, is now wandering around White Chalice, and observing with the curiosity of a child, but an unhurried patience of someone older.]

How interesting. To come up with something like this... Humanity really is something special.

[He comments while examining something, pretty much anything. It could be something strange and interesting, but on the other hand it could also be something ridiculously mundane.]
